Debate has long surrounded whether temperament and personality are distinct sets of individual differences or are rather two sides of the same coin. To the extent that there are differences, it could indicate important developmental insights concerning the mechanisms responsible for linking traits with outcomes. One way to test this is to examine the joint and incremental predictive validity of temperament and personality in the same individuals across time. Using a longitudinal sample spanning 3 decades starting at infancy and followed up to 37 years old (N = 7081), we ran a series of Bayesian generalized linear models with measures of childhood temperament and adult-based personality to predict outcomes in several life domains. Results indicated that while each set of individual differences were often related to the same outcomes, there were instances in which temperament provided incremental validity above adult personality, ranging from 2 to 10% additional variance explained. Personality in childhood explained the most variance for outcomes such as cognitive ability and educational attainment whereas personality performed best for outcomes such as health status, substance use, and most internalizing outcomes. These findings indicate childhood and adulthood assessments of personality are not redundant and that a lifespan approach is needed to understand fully understand life outcomes.

Personality traits predict both the initiation and continued usage of alcohol and drugs. Less established is if substance use is associated with subsequent changes in personality, especially during the sensitive period of adolescence. We used three approaches to disentangle selection and socialization effects to address whether substance use is associated with personality development (impulsivity, sensation-seeking, depression, self-esteem). First, we used a multi-wave longitudinal sample of adolescents (N = 8,303) from the National Longitudinal Survey of Youth - Child and Young Adult dataset to study the first use of several substances. Second, we used propensity score weighting to equate users and abstainers on a range of background variables. Third, we investigated changes before, during, and after initiation of substances. Overall, there was unique variability and effects in personality across time for average levels, trajectories, and magnitudes of change both between users and abstainers as well as within users of specific substances. Results suggest that initiation of substance use is associated with changes in personality; the specifics of which are largely contingent upon the substance being used. Impulsivity and sensation-seeking were the traits associated with the most change while cocaine and cigarettes were the substances associated with the greatest changes.
